10. Stir well and pour over the top of the brownie.
11. Let frosting cool and harden.

SERVING

NOTES
Carob powder can be purchased raw or roasted. I used roasted carob powder in this recipe because I like the flavor better than the raw carob.
The carob chips I used are made with turbinado sugar. There is a variety of carob chip that does not have sugar but these chips do not melt very well so I use the sugar ones for baking.
